It's probably a good time to point out that even though the team was winning, the locker room was given to Dak by fiat. After Tony was ready to play he wasn't even allowed to compete for the job Jerry had said was still his just a few weeks earlier. Instead of being the starting quarterback for America's team as he had been for a decade, his new job was running the scout team. It's not much different than expecting the locker room to line up behind a hot dog vendor.
It could turn out to be Jerry's biggest blunder since paying a king's ransom in picks and salary for Roy Williams while Miles Austin was riding the pine as a receiver and running back kicks. We'll find out sometime in the next month, or worst case, maybe even next year after Tony is gone.
I don't think it takes a genius to postulate that intentionally not starting your best quarterback in the playoffs could come back and take a big chuck out of your own behind.
